Failed test due to matplotlib deprecation of interactive_bk

[scottshambaugh]

I originally submitted this issue for debugpy microsoft/debugpy#1623, and saw on a linked issue that there is a comment tracking the issue back to PyDev.Debugger: microsoft/debugpy#1633 (comment)

I'm not sure if the issue is in this repo, but potentially this line is at fault?

PyDev.Debugger/pydevd.py

Line 695 in 54f8db4

self._gui_event_loop = "matplotlib"

Please see the linked tickets for details, but the end result is that I am unable to debug tests in VSCode via the Python extension right now. The following error is raised:

E       matplotlib._api.deprecation.MatplotlibDeprecationWarning: The interactive_bk attribute was deprecated in Matplotlib 3.9 and will be removed in 3.11. Use ``matplotlib.backends.backend_registry.list_builtin(matplotlib.backends.BackendFilter.INTERACTIVE)`` instead.

A workaround to make debug work is to ignore the warnings using:

In pyproject.toml (or other configuration file, adapt the syntax accordingly)

[tool.pytest.ini_options]

filterwarnings = [
    "error", # raise error on every warning, except the ones below
    "ignore::matplotlib._api.deprecation.MatplotlibDeprecationWarning",
]
